= Babson Collection, Suppl. p.4: "This first Amsterdam reprint of the second edition of the Principia is a fine example of bookmaking."; DSB X, p.42ff: "(...) Newton's masterwork was worked up and put into its final form in an incredibly short time. His strategy was to develop the subject of general dynamics from a mathematical point of view in book I, then to apply his most important results to solving astronomical and physical problems in book III. Book II, (...) is almost independent (...). As Karl Popper has pointed out, although "Newton's dynamics achieved a unification of Galileo's terrestrial and Kepler's celestial physics," it appears that "from a logical point of view, Newton's theory, strictly speaking, contradicts both Galileo's and Kepler's". (...) One of the most important consequences of Newton's analysis is that it must be one and the same law of force that operates in the centrally directed acceleration of the planetary bodies (toward the sun) and of satellites (toward planets), and that controls the linear downward acceleration of freely falling bodies. This force of universal gravitation is also shown to be the cause of the tides, through the action of the sun and the moon on the seas (...)."; cf. PMM 61. SEE ILLUSTRATION PLATE CXXVII.
